According to Mawlana in his book Liberating the Soul, ego is not part of the person. It is only attached to a person with function to protect the child before it attains mature age.
So what is ego? Is it some kind of executing software? In that book Mawlana only describe the bad ego. Is it the same as the good ego?
Could you please describe further what is nafs?
